Abstract

Self-focusing and self-phase modulation of cosh-Gaussian laser beam in a Kerr medium with linear absorption is studied. The field distribution in the medium is expressed in terms of beam width, decentered parameter and absorption coefficient. Numerical analysis shows that these parameters play vital role on propagation characteristics.
